All I have been doing was convert bitcoin to eth thats it but cant send any back out, trying 0.6.2 now but doing same thing wont keep sync after it loads up and still locks on trying to send, now deleted chain and redownloading maybe that will help.

We knew there was a very proeminent crowdsale that would benefit from it, but we never expected it would be as popular as it became. As a result, at each block the wallet was doing over 10k local database reads and writes, therefore causing the interface to stop responding and sometimes lose connection to the database. This bug was behind the dreaded "invalid date" error that affected many of our users.
